There are 8.6%~10.91% foreign matter in the sphenes, in which radioactive elements of strontium, cesium and uranium range from 4.26% to 4.58%. The change of structural cell parameters of sphenes is still very little,Δa=-0.0009 nm~0.0041 nm,Δb=0.0018 nm~0.0004 nm,Δc=0.0002 nm~0.0048 nm,Δβ=-0.10°~0.09° with high crystallinity of 99.27%~96.46%. Though, the age of sphene from the Fenghuang Mountain is about 1000 Ma, and experienced 775 Ma~1758 Ma geological evolvement and alpha decay, its crystallinity only decreased 3%, and its crystal shape and structure are still fine, indicating that sphene is of good ability to solidify radioactive elements. Therefore, sphenes are ideal minerals for solidifying nucleus waste.

通过对北祁连牛心山变质杂岩体中榍石(775Ma)和山西凤凰山花岗岩中榍石(1758Ma)的XRD及EDS等测试与研究，结果表明：两地榍石的杂质元素质量分数高达8.6%~10.91%，放射性核素锶、铯和铀的质量分数达4.26%~4.58%；晶胞参数的变化极小，△a=-0.0009nm~0.0041nm、△b=0.0018nm~0.0004nm、△c=0.0002nm~-0.0048nm、△β=-0.10°~0.09°，结晶度仍高达99.27%~96.46%，榍石经过10×10^8a的地质作用，结晶度仅减少了3%，显示榍石固化放射性系列核素的能力较强，虽经历了约775Ma~1758Ma的复杂地质演化及其所含放射性核素的衰变作用，其晶体结构完好，稳定性极高，是值得期待的理想核废物固化矿物。

The result indicates the t-BHP or diamide both cause the mass loss about the membrane protein thiol in hepatocytes, the fast oxidization about glutathione in hepatocytes, the leakage of lactate dehydrodenase, but the level of t-BHP is larger than of diamide. In the aspect of lipid peroxidation, only the t-BHP produces apparent change. As to actin and tubulin, they both find fall-off and present time-dependency effects. The result in Confocal fluorescent microscope also show these two cytoskeletal proteins are related to cell blebbing, but they don''t play the same role during the porcess. Tubulin may be more important than actin. If the study predispose dithiothreitol before adding t-BHP or diamide, then the damage by the diamide is repressed, but just partly protection for the damage by t-BHP.

结果显示t-BHP或diamide均可造成细胞膜蛋白硫醇大量流失与胞内GSH快速氧化，亦显著导致乳酸去氢□渗漏，但t-BHP诱发的渗漏程度大於diamide；在脂质过氧化方面，则仅t-BHP处理组产生明显的脂质氧化情形；至於肌动蛋白与管蛋白单体均可见减少且呈现时间依赖效应；在雷射共轭焦萤光显微镜观察中，亦显现这两种架构蛋白与细胞膜起泡有关，但两者在小泡生成的过程中扮演的角色并不完成相同，可能管蛋白较肌动蛋白重要；如果细胞在t-BHP或diamide加入前预先以dithiothreitol处理，则diamide 所造成的伤害显著的受到抑制，但DTT对t-BHP所诱发的伤害则仅有部分保护效果。

The study showed that the biosorption process could be described well by pseudo-second-order kinetic model and Freundlich isotherm model.Higher cell concentration was favorable to the biosorption.Temperature's effect on the biosorption was not obvious.The oxygenous and nitrogenous functional groups on the cell wall played a very important role in the process of biosorption.Microdeposits were formed by int...

结果表明，菌体对银的吸附量可达91.75 mg/g，吸附过程符合Pseudo-second Order吸附动力学模型，相关系数高达0.999 9；吸附热力学很好地符合Freundlich吸附等温模型，相关系数为0.99；考察菌体浓度和温度对吸附的影响发现，菌体浓度增加有利于对银离子的吸附，温度对吸附影响较小；FTIR、SEM及EDAX实验结果表明吸附存在2种吸附机理，一为菌体表面一些含氮氧的基团对Ag+的络合作用，二为菌体分泌的胞外多糖等物质对Ag+的微沉淀成晶作用。

The morphology of partial SW480 cells was shrunk volume, integrated cell membrane, condensed cytoplasm, pyknotic chromatin, nuclear fragmentation. Apoptotic Corpuscles were found by electron microscope.②MTT colorimetric assay showed quercetin inhibited the growth of human colon carcinoma cell line SW480 in a time- and dose-dependent manner when the concentration of quercetin was 30、60、90μmol/L.③Flow cytometry analysis showed the cell cycle of SW480 cell was restricted in G1/S. G0/G1 phase rate increased and S phase rate decreased with increasing concentration of quercetin and time lasting.④ Zymogram analysis assay showed the secretion of matrix metalloproteinases in human colon carcinoma cell line SW480 treated by quercetin decreased. With increasing concentration of quercetin, the secretion of MMP-2 and MMP-9 decreased.⑤Immunohistochemistry method demonstrated the position expression of Cathepsin-D in SW480 cell was suppressed by quercetin in a time- and dose-dependent manner.

研究结果：经槲皮素处理的人结肠癌SW480细胞数量减少，部分细胞体积缩小，细胞膜完整，胞浆浓缩，核染色质固缩，细胞核碎裂，形成凋亡小体；MTT法检测显示当作用浓度为30μmol/L~90μmol/L时，槲皮素对人结肠癌SW480细胞的生长有抑制作用，其抑制作用随着作用浓度的增加和作用时间的延长而增强；流式细胞学发现槲皮素主要作用于人结肠癌SW480细胞周期的G1/S期，大部分细胞被阻断于S期，随药物浓度的升高和作用时间的延长，G0/G1期细胞比例逐渐增加，S期细胞比例逐渐减少；酶谱分析法检测显示不同浓度的槲皮素能够抑制人结肠癌SW480细胞分泌MMP-2及MMP-9，随浓度的升高，MMP-2及MMP-9的分泌量减少；免疫组织化学法显示不同浓度的槲皮素处理人结肠癌SW480细胞后，Cathepsin-D的表达随药物浓度的升高和作用时间的延长而降低。

Of the above-mentioned immune molecules, microglia labelled with OX-42 or ED-1 were increased in their populations and staining intensity in LTA-treated rats than those in saline-treated ones. It is also true for OX-42 or ED-1 labelled macrophages in the meninges and the choroids plexuses.

Transport signal in a soluble cargo protein (for example, a secreted protein that passes through the lumen) is a region that binds to the lumenal domain of a transmembrane cargo receptor, which in turn has an cytoplasmic domain that binds an adaptor protein. Interaction between the cargo and the coat

我们已经有了几种类型的信号的细节：要求一种构像用于蛋白质通过胞吞作用成为细胞内的一部分；一种氨基酸序列使得蛋白质到达内质网；和一种修饰使得蛋白质到达溶酶体（小的膜体，在那里蛋白质降解，见后面）。

Importantly, we demonstrate that phagosomes containing internalized cell corpses are unable to fuse with lysosomes in vps-18 mutants.

因此，在凋亡细胞的清除过程中，具有正常降解活性的胞内体和溶酶体与含凋亡细胞的吞噬小体之间的正常融合，对于凋亡细胞的及时清除是至关重要的。

At experimental equilibrium volume, the total energy of CaTiO〓 increased with the displacement of Ti along [001] direction and the lowest energy point is always at zero displacement of Ti. However, with a 10% volume expansion, the displacement of Ti along [001] direction results in a shallow, but well-defined double energy well and ferroelectricity appears.

钛酸钙在实验晶胞体积下，钛离子沿[001]方向的位移不会引起总能量的降低，当体积膨胀10％时，钛离子的位移会引起系统的总能量的降低，在一定的位移时总能量呈现极小值，即出现铁电性。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
